Description of the walk

Car park in front of the Tourist Office, Rue du Sassin, in Bomal.

(S/E) With your back to the Tourist Office building, head towards the RN886. Cross towards the church.

(1) Take the stairs on the right, near the ramparts. Continue along the path closest to the road. Cross the bridge under the pergola, turn immediately left and walk between the buildings. Turn right straight away. At the end of the street, cross carefully and take Rue du Nofiot opposite. Continue up the street and walk past the schools. At the next crossroads, go straight on, ignore the path going up with the barrier and walk past the shed.

(2) Further on, take the path on your right. Go through a gate and, when the path branches off to the left, follow the fence. At the top, go through the other gate.

(3) Belvedere and viewpoint over Bomal. Continue along the path following the fence. Go through another gate and then another, continuing on the left. At the forest path, continue to the right and then go through the gate on your left. Climb up to the heights of Mont des Pins. View of Barvaux and its corn maze. Go through the gate and turn left. View of the village of Ozo in the distance.

(4) At the crossroads, turn right. Go downhill and at the Y junction, take the path on the left. At the end, turn left. At the end of the path, take the path on the left, close to the barrier, and go downhill to the Aisne.

(5) Cross the bridge, continue behind the gardens and you will come to the road. Cross and continue on the left. Take the first road on the right, "Lagalire", go up and ignore the road on the right. Take the hairpin bend and continue along the "Tombeux" road.

(6) After No. 13, take the path going uphill on your right, where you will see a large wooden cross. At the crossroads, turn left.

(7) Descend on your right and discover the Coléoptère cave. Then continue along the path, climb the stairs and turn right. At the Y, turn right and follow this path between meadows and forest. Further up, the path enters the forest and curves to the right. At the fork, continue to the left, then to the right just before the exit to the meadow. Continue along the forest path.

(8) At the end, turn left and pass in front of a cross. The path becomes a road. At the end of the road, turn left, pass in front of the church of Ozo on your right, continue straight ahead and pass in front of a chapel.

(9) Then take the road on the left, which turns into a path and leads to a road. Cross carefully and continue on the forest path opposite. Stay on the main path. At the fork, continue to the right, ignore the path coming from the left and walk to the next crossroads.

(10) Look for the opening in the fence, right next to the barbed wire gate. This opening is only wide enough for pedestrians. Look for the fence and tree withGR® markings opposite, on the other side of the meadow, and cross the meadow in that direction. Continue along the path on the other side and descend towards the RN86.

(11) Cross carefully, stepping over the guardrail to continue along the path. Continue to the left and you will reach Route de Saint-Cergue.

(12) Follow the road to the right and, after crossing the bridge over the Lembrée, you will come to a road. Take it to the right and then take the path to the left. Go through the first gate, go through the second, continue straight ahead and go through the third. Then turn left, ignore the paths and continue along the path until you reach the gate on your left.

(13) Go through it and you will find a viewpoint over the valley. Take the path down to the right and discover the Grotte Geneviève. When you reach the road, turn right and, a little further on, cross the small bridge on your left over the Lembrée. (If the bridge is still not there, see practical information.) Continue on your right and at the end of the path, take the road on the left to climb up to the ruins of Logne Castle.

(14) Retrace your steps a little and, with your back to the castle, take the path that branches off sharply to the right. Descend and you will find yourself back on the Route de Saint-Cergue.

(12) Cross the street and take the path you took on the way there, passing behind the houses. Walk back up to the road.

(11) Go through the gate and follow the path up to the meadow, which you cross.

(10) At the crossroads, take the path on the right.

(15) Further on, pass in front of the Saint-Rahi Chapel. At the crossroads, continue straight ahead and then, further on, take the path on your left leading into the woods. Cross the Izier road and continue along the forest path opposite.

(16) At the two remarkable lime trees, take the road to the left. Continue and, after the low walls, turn left towards the viewpoint.

(17) With your back to the viewpoint, take the path directly to the right. Go straight down at each junction, then at the fourth junction, turn right and go around the rock. Go down the stairs and pass under a tunnel carved into the rock

(18) At the fork, turn right and walk to the "Trou des Nûtons" cave and back.

(18) Continue down the path. Follow the main path to the bridge, cross the Aisne river and take the path to the right. Walk behind the football pitches, cross the stone bridge on your right, continue to the left and walk along the ramparts to return to the church.

(1) Cross the road and turn left to return to the car park (S/E).

Hello,
At point (5), it was impossible to cross; the bridge had been washed away in the 2021 floods. We turned left across a meadow, went through a fence and entered a large private meadow with a house on it. We crossed the river via the house’s private bridge and rejoined the road on the left.
A lovely walk, in glorious spring sunshine.

Hello,

We went on the hike knowing that there were no bridges. At point (5), we crossed the Aisne barefoot, which was very refreshing. Be careful, the pebbles are slippery.
As for the bridge at point (13), a new bridge has been built.

Overall, it was a very beautiful walk with stunning views and varied scenery.

Many thanks

Hello Vanderbeck Didier,
I mentioned at the beginning that the bridges were no longer there since the floods. An alternative route for the GR has been set up further upstream, but it involves a lot of road walking.
I am nevertheless sorry to hear that the footbridges have not yet been replaced. Many other things have undoubtedly been prioritised by the local council in the clean-up operation following this catastrophic event.

A very interesting route up to point 4. Unfortunately, there are no bridges over the Aisne, so you have to turn back and retrace your steps along the entire GR, which does not offer an alternative route to continue the hike. However, all the local council needs to do is install two or three concrete slabs to cross the rather turbulent river on this day, 11 March 2023. Ultimately, Belgium is the only country where a GR is impassable due to this kind of hazard...

Hello Pegase,
your message confirms that, unfortunately, the bridges have still not been replaced...
i was hoping that this would be fixed quickly at (4) since it is part of the GR57 trail.
I will check with the local council to find out if this is planned for the coming months. For the time being, I will leave the comment about the possible ford in the explanatory note at the beginning of the description.
For (12), you can take a detour via the Domaine de Palogne to climb up to the ruins and then rejoin the route. Perhaps you didn't have the Visorando app, because with a map it was possible to get around the problem.
In any case, I will add the information to the "practical information" section so that at least the alternative of the (12) can be provided.

Thank you for your feedback
Best regards

A very beautiful, fairly hilly route. Avoid if it has rained heavily the day before, as the second half is very muddy and even dangerous on the descent after the Geneviève cave. Two bridges are missing: the one over the Aisne at point 4 and the one over the Lembrée at point 12. At point 4, the river was in flood and rather dangerous to ford, so I went through the private property on the left, which is obviously not advisable. At point 12, I didn't see a bridge, so I skipped the ruins of Fort Logne, which was a shame... The route needs to be corrected given the lack of bridges, especially at point 4, where there are no alternatives.

we have just finished the hike. Magnificent. The bridge is not broken at point 4, only cluttered with trees and debris from the floods. Given the sign after the bridge saying "STOP PRIVATE", the residents are not going to do anything to remove all the wood cluttering up the bridge. The water was not too cold. Thank you

Hello Arina,
thank you for your feedback.
The floods have had consequences everywhere, and I understand that local authorities have other priorities than rebuilding bridges/footbridges for walking routes.
That's what makes it an adventure
But I will write all this in the description of this hike.

I look forward to hearing from you on another of my hikes

A beautiful walk with magnificent views. However, the route requires a few changes. The bridge between points 4 and 5 is broken. This means you have to cross the river barefoot because the water is almost knee-deep. The bridge that should lead to La Lembrée after point 12 has also disappeared. I had to find another way to get back to the starting point.
